Great Buy....

Installed on 1999 Jeep Grand Cherokee Limited WJ (4.7L 287 CID Quadra-Drive). Came the day after I ordered it and had it installed in less than half an hour. Quick and easy. Great for better gas mileage (went from about twelve mpg to about fourteen mpg, not much but when its that low anything helps), and a couple extra horses. Only dislike was that the tuner does not change speedometer for bigger tire sizes. But other than that GREAT BUY!!!

I bougt this unit for my stock Grand Chereokee `94. It is easy to install, I only had to pick out the can for the coolant. The electronic and engine is in a better balance and more straight than before. For this price, this is an unbeatable tune up.
